I'd avoid that, maybe you can clone your current Catalina to another external drive it's safer, however the signal when an EFI/SMC update ongoing is that is showed a big apple logo with big loading bar, then followed sometimes by some beeps.

I guess so, I mean it should work too using an El Capitan OSInstall.mpkg.
Yes, the mbp showed the apple logo with the big bar but didn’t filled it before rebooting, and no bip at all.
Idk if it has already been said but on the early 2008 mbp, i have this when i launch the catalina loader.

Rastafabi's Catalina loader
READ THIS ENTIRE POST AND THE INCLUDED README FIRST!
It took me a while, but finally I managed to create a "Catalina loader", which enables you to install macOS 10.15 Catalina on unsupported Macs with compatible hardware. It's meant for Mac Pro 4,1 & 5,1 and iMac 2010/2011 systems, which have a Metal compatible GPU. A upgraded WiFi/Bluetooth card might be necessary to have OOB support. I have not yet looked into audio, though on my Mac Pro 4,1 it works OOB. The download includes an installation guide with additional details.
It is not meant for systems without a Metal GPU or with Core2 Duo (based) CPUs.
The loader is based on rEFInd and OpenCore, which spoofs the Mac to be a compatible model.

Some might be reminded of my old Mavericks download enabler.

Dual CPU Mac Pros also require to be running non x55xx CPUs to omit audio stuttering. Thanks @tsialex

Questions:
The Catalina Loader is confirmed to work with the first macOS Catalina developer beta installer (DP1).
No other installers have been tested and thus are not supported at the moment as those can potentially damage your hardware.
Properly not, as I think the installer will complain about not having a metal compatible GPU. Feel free to test and report.
Just about any should work. Find an old 512mb drive and you are good to go. Of course larger drives will work, too. BTW: You may also use SD-Cards, if your Mac can boot from those.
You can't. Just install it manually afterwards. There is now way to add anything, as this basically just enables you to run the legit unmodified Catalina installer.
I am very sorry. However there is nothing I can do. You have been warned (README) and proceeded at your own risk.

Updates:
- Fixed large file size (60mb), due to an oversight one may part.
- Removed experimental flag causing issues.
Thx for the updates, btw won't be a better solution to spoff the VMM flag?

You're totally right!
If I don't get wrong no EFI/SMC firmware.pkg should be processed during an OSX VM installation.
Yes, and Distribution file will bypass any restrictions:
Code:
var cpuFeatures = system.sysctl( 'machdep.cpu.features' );
cpuFeatures=cpuFeatures.split(" ");
for( var i = 0; i < cpuFeatures.length; i++ ){
if( cpuFeatures[i] == "VMM" ){
return true;
}
}
I successfully booted a clone on my hacked book MBP5,2 from a supported Mac. Unfortunately, my MBP5.2 keyboard and the sound are not working. I have tried old AppleHDA from 10.14.5 and other AppleALC, to no avail.
Much worse is the keyboard of the MBP 5.2 does not work. Does anyone have any tips for me?

I've been working on an installer patch, which I think I've gotten just about done at this point.
awesome work bud! how's the website?
Thank you for the quick fix kind sir
HI! i was losing all hopes, then I have read this wonderful news. If you think that it is possible, my Macmini 2010 is ready for testing Catalina :-D
It works very well with Mojave 10.4.5 patched by @dosdude1 If you modify the old installer I could try to install beta 1 tonight

Probably a silly question, but is my card supported by Catalina or is it time for another upgrade or a kext?
Card Type: AirPort Extreme (0x14E4, 0x8E)
Firmware Version: Broadcom BCM43xx 1.0 (5.106.98.102.31)

Let us know when the macOS beta 1 patch will be available to test, and the Mac that could be compatibile, also if still unstables. I have a macmini 2010 (Macmini 4,1) with Nvidia Geforce 320M and 8 gb RAM, if you need a test unit. But I need Core 2 duo patch, too. :-D

I'm waiting for @dosdude1's installer patch. Then I can release macOS Patcher 3 beta 1. The machine support is the same as Mojave. Pretty much, if it can run El Cap officially and can't run (High) Sierra and/or Mojave then it's supported. The exception to this is the MacBook4,1 which can officially only run up to Lion but will actually support even Catalina in macOS Patcher 3.
I can say that on a 2007 iMac and spoofing it to think it is a late 2012 iMac using Clover, I have never ran into any firmware update problems. I still couldn't get the Catalina loader to work so that is what I am doing now. Im still using the
- sudo nvram boot-args="-no_compat_check"
to be sure it installs. Right now I have about 20 minutes left on the upgrade to see how it works
Sadly not so interesting in the end.
Catalina does not provide any new firmware updates to my knowledge.
I did not check, weather it stores current ones. If so it’s interesting, as the spoofed firmware is 137.0.0.0.0, while the newest iMac one is 138.0.0.0.0.
Nonetheless great to know, that it works seamlessly on other i generation CPUs. Not having graphics acceleration is expected, of course.
As I wrote earlier, the dosdude1's Mojave Patcher, I mean the "Post Install" part updating it with all the @ASentientBot's Catalina (amazing) patches will still work as is for an already installed Catalina.
I guess he is trying to combine in one only Catalina Patcher the Installer and Post Patcher for all the unsupported Catalina Mac.
I'd say that on a real Mac "Catalina loader" is safer than Clover, since the first is based on Refind that is based on Refit .
The only time I used Clover on a real Mac was into a virtualbox VM.
Anyway hope to not encounter the big apple with big loading bar in the middle of Catalina installing.
The latest firmware came with the 10.14.6 Beta 2 update and brought new firmware to all supported machines but the cMP 5,1 (As @tsialex mentioned here: https://forums.macrumors.com/thread...ac-pro-2013-6-1.2085886/page-40#post-27452296)
I'm looking for patch mac Os catalina 10.15 for macbook pro I5 MacBookPro8,1 or e Catalina loader.zip thank. you
I’m looking for a brand new Ferrari or Porsche thank. you
Installing now on my iMac, shutted down when he wanted to install the smc update, I hope it will finish installing anyway...
I'm scared of these updates now
But if you have installed one Catalina, why don't you cloned instead of risking unwanted firmware update.
Although you will not get any answers to questions here (eg why the keyboard does not work in Catalina)
you probably do not like hackintosh users like me, but I still want to report that on my hack-book,
an Intel Medion Akoya P8610, everything like WiFi , Sound, trackpad, keyboard, etc. works.
I found it out myself without help from here. Only the transparency is not yet, but I also solve the problem.
Nevertheless, many thanks for the useful hints from here to get Catalina on the device at all to get.
